40.5kV YBO prefabricated substation (European style)

40.5kV European box transformer is a pre-installed substation designed and manufactured by Hechong Technology using advanced technology and design concepts for special customers. It is an organic combination of high-voltage switchgear, distribution transformer, low-voltage switchgear, electric energy metering equipment and power compensation device, and the whole is assembled in a relatively closed shell. At the same time, the high-voltage switchgear adopts the 40.5kV SF6 gas-insulated metal enclosed high-voltage cabinet independently developed by our company, which has the advantages of high power supply reliability and convenient maintenance. Box transformer reasonable layout, high protection level; reasonable structure design, modular assembly design, flexible transportation and installation, simple and convenient operation; beautiful appearance and environment integration and other outstanding advantages, mainly suitable for new energy projects, high-speed projects, export overseas, etc.

Product Parameters

Performance characteristics

(1) Compact structure, small size, small footprint, and convenient module functional design, transportation and installation.

(2) The shell can be made of steel plate, composite plate, non-metal and other materials, which is strong, heat-insulating, dustproof, moisture-proof, and small animal-proof.

(3) High degree of automation: The whole station can be designed intelligently according to the needs. The protection system adopts the substation microcomputer integrated automation device, which is installed in a decentralized manner, which can realize "four remotes", complete relay protection functions, and meet the requirements of unattended.

(4) factory prefabricated type: all equipment in the factory once installation, commissioning qualified, truly realize the substation construction factory, shorten the design and manufacturing cycle.

(5) the combination of flexible: European box variable due to the compact structure, each box constitutes an independent system, which makes the combination of flexible.

(6) investment province, quick results.
